Herbal Shampoo for Colored Hair with Dandruff

To create a shampoo that addresses both colored hair and dandruff concerns, you can combine a gentle shampoo base with specific active ingredients.

Recommended Ingredients:

• Sulfate Free Shampoo Base (pH 7, Clear, Foaming): A sulfate-free base is recommended for colored hair as sulfates can strip color. This base is gentle and suitable for hair cleansing products.
• ColorFix™ (helps hair color stick better): This ingredient is designed to help semi-permanent hair color adhere better and last longer. It has cationic properties that coat the hair. Note: The description mentions that for semi-permanent hair color, adjusting the shampoo pH to not lower than 8.0 can help color attach better when using ColorFix™. The Sulfate Free Shampoo Base has a pH of 7, so you may need to consider pH adjustment if using semi-permanent color, or test the formula's effectiveness with your specific hair color.
• Dandruff-Guard™ (Piroctone Olamine): This is an effective anti-dandruff ingredient that targets the fungus causing dandruff. It can be used in rinse-off products like shampoo.

Basic Formulation Example:

Here is a basic structure. You will need to adjust percentages based on desired performance and regulatory limits.

• Sulfate Free Shampoo Base (pH 7, Clear, Foaming): 25-35% (refer to product description for usage rate)
• Dandruff-Guard™ (Piroctone Olamine): 0.5 - 1.0% (maximum 1.0% in rinse-off products according to FDA Thailand)
• ColorFix™: 0.6% (recommended for shampoo)
• Water: Balance to 100%
• Preservative: As needed (follow supplier's recommendation)
• Optional: Herbal extracts, fragrance, thickener (note that Dandruff-Guard™ can affect viscosity), pH adjuster (if needed, especially considering ColorFix™ note).

Mixing Instructions:

1. Mix the Sulfate Free Shampoo Base with water according to its usage instructions.
2. Disperse Dandruff-Guard™ in a small amount of water first before adding it to the shampoo base mixture. Stir gently until dispersed.
3. Add ColorFix™ to the mixture and stir to combine.
4. Add preservative and any other optional ingredients (herbal extracts, fragrance).
5. Adjust pH if necessary, keeping in mind the note about ColorFix™ and semi-permanent color.
6. Stir gently to avoid excessive foaming.

Always perform small-scale tests first and adjust the formula as needed. Ensure all ingredients are compatible and follow recommended usage rates and safety guidelines.
